GDM Greeter Crashing FC2

[Eucke <euckew@xxxxxxxxxxxxxxxxxxxxx>]

Hello Everyone,

I am hoping someone who's experienced this problem can point me in the 
right direction.  The machine in question is a basic build and has long 
been stable.  After installing the most recent updates I ended up 
rebooting.  When the machine came up I did as I normally do.  I SSH'ed 
in, SU'ed to root and then manually invoked the VNCServer.  Within a 
couple of minutes the server hard locked on me.  I did not discover this 
until a few hours later.  What I found was a message in the logs that 
indicated that  "The greeter program appears to be crashing. I will 
attempt to use a different one."  However, from what I can tell, the 
system was completely unresponsive.  None of the services running on the 
server appeared to be live from outside the box...and no response at the 
local console.

From what I have been able to dig up there appears to have developed 
some toxic relationship between VNC, KDE and the Greeter when you SU in 
SSH.  The system has long been stable so it's something that was 
recently changed.  I feel like I am nibbling all around the fix but 
cannot seem to identify it.  What am I missing?  I really appreciate any 
help on this.  Nothing that I have turned up via google has helped me 
pinpoint or determine the fix.  Thank you!
